Earth Anchors, Second Edition

Anchors are primarily used in the construction of foundations of earth-supported and earth-retaining structures. The fundamental reason for using earth anchors in construction is to transmit the outwardly directed load to the soil at a greater depth and/or farther away from the structure. Although earth anchors have been used in practice for several hundred years, proper theoretical developments for purposes of modern engineering designs have taken place only during the past 40 to 45 years. This book summarizes most theoretical and experimental works directed toward the development of proper relationships for the ultimate and allowable holding capacity of earth anchors.

KEY FEATURES:

--A discussion on single-helix screw anchors in sand has been added to Chapter 6
--Two new chapters have been added: Suction and Caisson Anchors (Chapter 9) and Geo-Anchors (Chapter 10)
--A summary section and self-assessment multiple-choice questions, with answers, are provided at the end of each chapter
--Details horizontal, vertical, and inclined anchor plates, helical anchors, and anchor piles
--Reviews the failure mechanism in soil located around the anchor as well as various theories to calculate the ultimate and allowable loads
--Includes laboratory and field test results to supplement and verify the theories in the book
